2.3.2 Hard Disk Space Requirements

This section lists system requirements for Windows platforms that use the NT File System (NTFS). Note that FAT32 File Systems are not supported. Oracle recommends installing Oracle components on NTFS.

The NTFS system requirements listed in this section are more accurate than the hard disk values reported by the Oracle Universal Installer Summary window. The Summary window does not include accurate values for disk space, the space required to create a database, or the size of compressed files that are expanded on the hard drive.

The hard disk requirements for Oracle Database components include 32 MB required to install Java Runtime Environment (JRE) and Oracle Universal Installer on the partition where the operating system is installed. If sufficient space is not detected, installation fails and an error message appears.

The 3.02 GB of disk space for the Oracle home is the disk space for the Oracle Audit Vault Server software files in the Oracle Base including 1.49 GB of disk space for the Oracle Audit Vault database files. The TEMP space required is 108 MB.

The 1.49 GB of disk space for the Oracle Audit Vault database files is only if the database storage option is on the file system. For other storage options, such as ASM, the database files will be stored elsewhere. Also, this 1.49 GB disk space is only the starting size. The Oracle Audit Vault administrator must take future growth of the database size into consideration, especially as the server collects more and more audit data.

2.3.3 Verifying Hardware Requirements

To ensure that the system meets these requirements, perform the following tasks:

Determine the physical RAM size. On a Microsoft Windows Server 2008 computer, click System and Security in the Windows Control Panel, then click System.

If the size of the physical RAM installed in the system is less than the required size, then you must install more memory before continuing.

Determine the size of the configured virtual memory (also known as paging file size). On a Microsoft Windows Server 2008 computer, click System and Security, then click System, click Advanced System Settings, click the Advanced tab on the System Properties page, and then click Settings in the Performance section. Then select the Advanced tab on the Performance Options page.

The virtual memory is listed in the Virtual Memory section.

If necessary, see your operating system documentation for information about how to configure additional virtual memory.

Determine the amount of free disk space on the system. On a Microsoft Windows Server 2008 computer, right click My Computer and click Open.

Determine the amount of disk space available in the temp directory. This is equivalent to the total amount of free disk space, minus what is required for the Oracle software to be installed.

If there is less than 100 MB of disk space available in the temp directory, then first delete all unnecessary files. If the temp disk space is still less than 100 MB, then set the TEMP or TMP environment variable to point to a different hard drive location.

On a Microsoft Windows Server 2008 computer, click System and Security, then click System, click Advanced System Settings, click the Advanced tab on the System Properties page, and then click Environment Variables.

2.4 Checking the Operating System Requirements

Oracle Universal Installer performs checks on your system to verify that it meets the listed requirements. To ensure that these checks pass, verify the requirements before you start Oracle Universal Installer.

The platform-specific hardware and software requirements included in this installation guide were current at the time this guide was published. However, because new platforms and operating system software versions might be certified after this guide is published, review the certification matrix on the My Oracle Support Web site for the most up-to-date list of certified hardware platforms and operating system versions. This Web site also provides compatible client an database versions, patches, and workaround information for bugs. The My Oracle Support Web site is available at the following URL:

2.5.1 Windows Terminal Services and Remote Desktop Support

Oracle supports installing, configuring, and running Oracle Database through Terminal Services on Microsoft Windows Server 2008. If you encounter problems with the installation through Terminal Server, Oracle recommends that you try connecting to the Terminal Services console session of the server (using mstsc/console).

You can have multiple Remote Desktop sessions on Microsoft Windows Server 2008.

2.5.2 Web Browser Support

The following Web browsers are supported for iSQL*Plus and Oracle Enterprise Manager Database Control:

Netscape Navigator 7.2 and later

Microsoft Internet Explorer 6.0

Mozilla version 1.7 and later

Safari 1.2

Firefox 1.0.4

2.6 Checking the Network Setup

Typically, the computer on which you want to install Oracle Audit Vault Server is connected to the network, has local storage to contain the Oracle Audit Vault Server installation, has a display monitor, and has a CD-ROM or DVD drive.

This section describes how to install Oracle Audit Vault on computers that do not meet the typical scenario. It covers the following cases:

2.6.1 Installing on DHCP Computers

Dynamic host configuration protocol (DHCP) assigns dynamic IP addresses on a network. Dynamic addressing enables a computer to have a different IP address each time it connects to the network. In some cases, the IP address can change while the computer is still connected. You can have a mixture of static and dynamic IP addressing in a DHCP system.

In a DHCP setup, the software tracks IP addresses, which simplifies network administration. This lets you add a new computer to the network without having to manually assign that computer a unique IP address.

Do not install Audit Vault Server in an environment where the IP addresses of the Audit Vault Server or the Oracle Audit Vault collection agent can change. If your environment uses DHCP, ensure that all Oracle Audit Vault systems use static IP addresses.

2.6.2 Installing on Multi-homed Computers

You can install Oracle Audit Vault on a multi-homed computer. A multiple-homed computer has multiple network cards, which in turn, allows it to have multiple IP addresses. Each IP address is associated with a host name. In addition, you can set up aliases for the host name. By default, Oracle Universal Installer uses the ORACLE_HOSTNAME environment variable setting to find the host name. If the ORACLE_HOSTNAME environment variable is not set and you are installing Oracle Audit Vault on a computer that has multiple network cards, then Oracle Universal Installer determines the host name by using the first entry in the hosts file, typically located in SYSTEM_DRIVE:\WINDOWS\System32\drivers\etc.

Clients must be able to access the computer using this host name, or by using aliases for this host name. To check, ping the host name from the client computers using the short name (host name only) and the full name (host name and domain name). Both must work.

Setting the ORACLE_HOSTNAME Environment Variable

To set the ORACLE_HOSTNAME environment variable:

From the Start menu, click Control Panel.

Click System and Security, then click System.

Click Advanced System Settings.

Click the Advanced tab on the System Properties page, and then click Environment Variables.

In the Environment Variables dialog box, under System Variables, click New.

In the New System Variable dialog box, enter the following information:

Variable name: ORACLE_HOSTNAME

Variable value: The host name of the computer that you want to use.

Click OK, then in the Environment Variables dialog box, click OK.

Click OK in the Environment Variables dialog box, then in the System Properties dialog box, click OK.

2.6.3 Installing on Computers with Multiple Aliases

A computer with multiple aliases is registered with the naming service under a single IP address, but with multiple aliases. The naming service resolves any of those aliases to the same computer. Before installing Oracle Audit Vault on such a computer, set the ORACLE_HOSTNAME environment variable to the computer whose host name you want to use.

2.7 Creating Directories for Oracle Audit Vault Database Files

If you choose to place the Oracle Audit Vault database files on a file system, then use the following guidelines when deciding where to place them:

The default path suggested by Oracle Universal Installer for the database file directory is a subdirectory of the Oracle base directory.

You can choose either a single file system or more than one file system to store the database files:

If you want to use a single file system, then choose a file system on a physical device that is dedicated to the database.

For best performance and reliability, choose a RAID device or a logical volume on more than one physical device and implement the stripe-and-mirror-everything (SAME) methodology.

If you want to use more than one file system, then choose file systems on separate physical devices that are dedicated to the database.

This method enables you to distribute physical I/O and create separate control files on different devices for increased reliability. It also enables you to fully implement the OFA guidelines.

For optimum performance, the file systems that you choose should be on physical devices that are used only by the database.

The user with Administrators privilege or who is a member of the ORA_DBA group performing the installation has write permissions to create the files in the path that you specify.

2.8 Setting the Correct Locale

Ensure that the NLS_LANG environment variable is not set. On a Microsoft Windows Server 2008 computer, click System and Security, then click System, click Advanced System Settings, click the Advanced tab on the System Properties page, and then click Environment Variables. Then under System Variables look for NLS_LANG. If NLS_LANG is set, remove the setting by selecting it and clicking Delete, and then click OK to save your change.
